1. Close all GUI connections to the SQL Server.
2. Ensure that no SQL Backup jobs are in progress.
3. Stop the SQL Backup Agent Service, or disable the cluster resource if on a cluster.
4. On the SQL Server where the SQL Backup server components are installed, navigate to the installation directory. Defaults are:

5. In the folder you will find an existing SQBCoreService.exe and SQL BackupC.exe. Rename the existing files, for example to OLDSQBCoreService.exe and OLDSQLBackupC.exe.
6. Now copy in the files extracted from the downloaded zip.
7. Restart the SQL Backup agent service/cluster resource, and ensure that it starts successfully.
8. Perform a test backup to ensure that all is OK. Then test to see if the original error occurs.

Thanks for the reply Peter. What is this error? We have been using this version for almost 3 years, we have clients who are receiving backups from us in this version. Management is reluctant to make changes. Why did this error happen all of the sudden?

The server that is taking the backup is running Redgate backup version 5.3.0.178. The server that we are attempting a ‘partial’ restore on is running version 6.4.0.56. How would this change the solution to our problem? What cost/work is involved in upgrading version 5 listed above to the version to sent me 6.5.2.23?
